WAR and Wrath: Important Mechanics Discussed.

[Gamemako]

Monsters have defense values that you're just flat out ignoring. Hell, with maim and storm eye on a random level 45 mob in Mor Dhana I just hit inner beast for 389. Obviously with maim and storm's eye. LEVEL 45.

I stopped doing theorycraft on damage formula in phase 3, when there were no defense values whatsoever. The damage formula did not change from phase 3 to 4, but I never checked for any new implementation of defense. I will have to go back and test again to see about any potential enemy defense or leveldiff reductions.

//EDIT: You have 320 strength. Kunnka has 423. Valk's formula predicts you do 392.44 damage per IB. I think there's no issue here, and no enemy defense.
